WILLIAM H. DOANE, OF CINCINNATI, OHIO.

DUPLEX PLA/NING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 365,507, dated June 28, 1887.

Application filed April 15, 1886. Serial No. 198,971. (No model.)

To all whom it may concern: Be it known that I, WILLIAM H. DUANE, a citizen of the United States, residing at Gincinnati, in the county of Hamiltonand State of Ohio, have invented certain new and'useful Improvements in Duplex Planing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to'make and use the same.

My invent-ion is in the nature of animprovement upon the class of duplex planing and matching machines, an example of which is illustrated in my United States Patent No. 335,994.; and its object is to enhance the. efficiency of this style of machines.

My improvement consists of certain combinations, separately set forth by distinct claims at the close of this specification, designed to simplify the mechanism for adjusting the feedrolls; also of the combination, with the lower planer knives, of independently adjustable pressure-bars.

In order that my invention may be clearly understood, I have illustrated in-the annexed drawings, and will proceed to describe, a prac-' tical form thereof.

Figure 1 represents a side elevation of so much of a duplex planing and matching machine as suffices to illustrate the embodiment Fig. .2 represents a plan view of the same, from which the mechanism for' adjusting the upper feedingin rolls-and upper feeding-out rolls, as well as the pressure-bars over the lower planing-cylinders, are omitted for the sake of clearuess of illustration Fig. 3 represents a cross-section of the machine, taken in the plane indicated by the line X X on Fig. 2; also showing the adjusting mechanism of one rank of upper feeding-in rolls in section. Fig. 4 rep- .resents a plan view of the upper feeding-in rolls and the mechanism for adjusting them. Fig. 5 illustrates the matcher-works, showing therelation of the upper planing-cylinders thereto. Fig. 6 represents a cross-section of the machine, taken in the plane indicated by the broken line 3 3; of Fig. 2, showing one of the pressure-bars in section. Fig. 7 represents a plan view of the duplex pressure-bar overthe The same letters of reference indicate identical parts in all the figures.

The machine in its general construction is similar to the machine described in my aforesaid United States Patent No. 335,994, and

parts not particularly described in this specification or omitted from the drawings may be constructed and organized in substantial accordance with the machine described in said patent. r

On each side of the machine there is an upper primary feeding-in roll, A, and an upper assistant feeding-in roll, B, all of which rolls are mounted and geared, substantially as described in my aforesaid patent. Thus the ma chine has two ranks of upper feeding-in rolls,

of which those marked B and A on one side of the machine constitute one pair, and those on the other side constitute another pair, and the machine is provided with a guideway for the material to be operated on for each of these ranks. With each of these upper feeding-in rolls is associated a lower feeding-in roll, two of which, A A, are clearly shown in Fig. 3. These lower feeding-in rolls are independent of each other, like the upper feeding'in rolls with which they are associated, and being journaled in independent boxes can be adjusted independently to the limited extent required. The primary upper feeding-in rolls are suspended from a hollow girder, O, and the assistant upper feeding-in rolls from a girder, D, in exactly the same way. The two j ournalboxes of each feed-roll A are suspended from the girder O by two screw-threaded spindles, E E and F F, respectively. The screwthreaded portions of these spindles engage screw-threaded holes on the backs of the boxes of the'upper feeding-in rolls. Screw-threaded spindles E and F terminate within the hollow girder O, and have respectively affixed to their upper ends bevel-wheels e and f. Similar bevelwithin the hollow girder, and these spindles E and F are extended through the topof the hollow girder, and have respectively affixed to their projecting ends spur-whcels e and f A shaft, E, journaled in suitable bear ings on the hollow girder G, is provided with bevel-wheels c and a, for driving the bevelwheels on the screw-threaded spindles E and E. A similar shaft, F, also journaled in hollow girder O, is provided with bevel-wheels f 3 and f, for driving the bevel-wheels on the screw-threaded spindles F and F. The outer end of shaft E is provided with a hand-wheel, E, and the outer end of shaft F is provided with a hand-wheel, F. A vertical stud, c, is provided on the top of hollow girder 0, midway between the spindles Eand F, on which stud a spurs-wheel, O, havinga handle, 0', may be placed as a connecting-wheel between the wheels e and f It will be observed that when the connect ing-wheel O is in gear with the wheels e and f both upper feeding-in rolls A A may be simultaneously adjusted from either side of the machine by turning hand-whcel E or F, as the case may be, and that on removal of the connecting-wheel 0 either feeding-in roll A may be independently adjusted. A suspension and adjusting mechanism, precisely similar to. that just described, is associated with the upper feeding-in rolls B B.

In order that all four upper feeding-in rolls may be simultaneously adjusted to like extent, the adjusting-shafts E and F are provided with sprocket-wheels E and F, which are connected by d rive chains and F with sprocketwheels of like diameter on the adjusting-shafts G and H of the upper feeding-in rolls B B.

The sprocket-wheels E and F can be slid on their respective shafts to be clutched to or unclutched from splines thereon. This arrangement of the sprocket-wheels E and F affords the means of adjusting the four upper feedingin rolls either simultaneously or independently. W'hen theinterconnecting wheel 0', of each adjusting mechanism is removed, the upper feeding-in rolls on one side of the machine may also be adjusted independently of the other feeding-in rolls on the other side of the machine.

A shifter-rod, I, may be provided for shifting the sprocket-wheel on the side of the machine remote from the side where the operator stands.

The upper planing-cylinders are mounted in bearings at the sides and in the center of the bed sliding upon standards A These bearings are moved upward and downward to effect the proper adjustment of the cylinders by means of the screws A. The cylinders are independently adjustable by means of the shafts A A A, which gear with such screws in the manner shown in Fig. 10, and serve as means of communicating motion. thereto. The conjoint adjustment of these cylinders is provided by a spur-wheel, B which can be attached to the crank B, and cause a rotation of said for dressing the under side of the boards is employed, I associate therewith two independently-adjustable pressure-bars, L L, for this rcason-namely, that each one of the two boards may be firmly held down even though the upper planing cylinder or cylinders have not reduced them to an even thickness. The use of these separate pressure-bars over the under planer is more especially desirable on a machine like the one illustrated, in which the upper surfaces of the two boards are dressed by short upper planingcylinders; but such separate independent pressure-bars may be used with advantage on machines which operate with a single long upper planing-cylinder. The pressure-bars L and L are respectively mounted on guides of a suspensionbeam P, and are suspended from said beam by screws H, by which they may be independ ently adjusted on the beam.

The suspension-beam P is mounted on the vertical posts of a yoke, M, and is suspended from the hollow horizontal bar of the yoke by vertical screw-spindles N and N, the upper ends of which are swivelcd on the yoke and provided with bevel-wheels, which mesh with bevel-wheels on the adj Listing-shaft O, mounted in the horizontal bar of the yoke. Each vertical post of the yoke is provided with a knuckle adapted to be pinned to lugs on the framework of themachino, so that by removing either pin the yoke, with its pressure-bars, may be turned up on the other pin, as indicated by the dotted lines in Fig. 6. It will be observed that by operating the adjusting-shaft O the suspension-beam may be raised or lowered to lift or lower the pressure-bars without changing their relative positions.

The feeding-out rolls consist of two independent upper rolls, Q Q, and two independent lower rolls. (Not shown in the drawings.)

These feeding-out rolls are mounted in the same conjointly or separately.

2. The combination, suhstantiallyas before set forth, vwith the four adj usting-shafts, of four pairs of screw-spindles for respectively supporting four feed-rolls, and the-two trains of gear-wheels, each of which trains contains a removable wheel for respectively connecting or disconnecting the two adjacent screw-spindles of each two associated pairs of said screwspindles, and two sets of chaingearing for connecting the four adjusting-shafts in pairs, whereby the four feed-rolls may be adjusted, either conjointly or by pairs.

3. The combination, substantially as before set forth, with the four adj usting-shafts, of four pairs of screw-spindles for respectively supporting four feed-rolls, and the two trains of gear-wheels, each of which trains contains a removable wheel for respectively connecting or disconnecting the two adjacent screw-spindles of each two assooiatcdpairs of said screwspindles, and two sets of chain-gearing for connecting the four adj usting-shafts in pairs, one sprocket-wheel of each set of such chain-gearing being adapted to be clutched to or unclutched from its shaft, whereby the four feedrolls may be adjusted, either separately or conjointly or by pairs or by ranks.

4. In a duplex planing-machine, the combination, substantially as before set'forth,with the lower planer, of two independently as well as conjointly adjustable pressure-bars.

5. In a duplex planing-machine, the combination, substantially as before set forth,with two independent lower planing-cylinders, of

twoindependently as wellas conjointly adjust- I two upper planing-cylinders and the lower planer, of two independently as well as conjointly adjustable pressure-bars over the lower planer.

7. In a duplex planing-machine, the combination, with two independentlyadjnstable top planing-cylinders placed over different longitudinal vertical sections of the bed-plate of the machine, of a lower planer and two independently and conjointly adjustable pressure-bars coacting with said lower planer, substantially as described.

8. In aduplex planing-machine having two guideways for separate pieces'of material, the combination, with two independently-adjustable top planing-cylinders, one for each guideway, of a lower planer and two conjointly and independently adjustable pressure-bars coacting with said lower planer, substantially as described.-

9. In a duplex planing-machine having two guideways for separate pieces of material, the combination, with two independently-adjust able top planing-cylinders, one for each guideway, of two lower planing-cylinders and two independently and conj oi ntly adjustable pressure-bars coacting with said lower planing-cylinders, substantially as described.

10. In a duplex planing-machine, the combination, with a lower planer. mounted in bearings in the main frame, of two independently and conjointly adjustable pressure-bars, each adjustment being positive, each of said pressure-bars coacting with a different longitudinal portion of the lower planer, substantially as described. j

11. In a planing-machine, the combination, with alower planer consisting of two independent planingcylinders, each of said cylinders occupying different longitudinal sections of the machine, of two independently and conjointly adjustable pressure-bars coacting with said cylinders, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
